I found Karina dresses via Instagram - they only make dresses and skirts, and the photos used are of a really wide variety of 'real people' models : tall, short, slender, curvy, pregnant, long legs, long waist, younger, older, a genuine range. It's very refreshing. Even though they're in the US I've ordered several dresses that have fitted just fine, because I already know pretty much what it's going to look like on me.
I would love it if Boden - or another mainstream clothing line - would use some of the 7 or 8 detail photos they currently have of each item on their website to show it on different body types. Stand by the design, Johnnie! If you're so insistent that this 'suits everyone', then let's see it.
